RGI has carried out an anoxic disinfestation treatment against xylophagous insects (woodworms) on some valuable wooden furnishings inside the Archives of the Chapter of the Cathedral of S. Maria del Fiore in Florence.
The archive houses over five thousand documents covering a chronological span of over a millennium, from the Carolingian period to date.
In the picture, you can see the anoxic intervention carried out through the creation of several enclosures made of a special gas barrier film, where a modified atmosphere was created inside with the VELOXY® System.
No chemicals harmful to man or the works were used, only nitrogen, a gas that is normally present in the air we breathe.
